Modbus Interface Output Ac Motor Protection Controller

Product Name: WDH-31-200 Modbus interface analog output ac motor protection controller

The motor protection controller can replace the electrical components such as thermal relays, time relays, transmitters, etc., simplifying the traditional motor control protection mode, and its protection range is wider, the precision action is more accurate and reliable, and the troubleshooting is more intuitive when the fault occurs, which can help the customer quickly. Determine the cause of the failure and reduce economic losses
